Description

Talk about cult followings -- Dumonde Tech Bicycle Chain Lube (BCL) has it like no other lube we've ever carried. According to virtually anyone who's ever tried it, BCL will keep your drivetrain components cleaner, lets them last longer and allow them to run quieter than what you'd get from any other lubricant out there. BCL forms a long-lasting coat on all chain surfaces. As you ride, it forms a low-friction plating which bonds to the chain and can't be washed off. It's environmentally sensitive and it's extremely durable, as one ounce should provide roughly 10 applications.

To get the best results from BCL, first clean your chain and dry it thoroughly prior to the first application. This effectively primes the surface for the "plating" effect that makes BCL so successful. For the first application, we recommend putting one drop on each link to really aid the plating effect, wiping the excess from the chain after it has had time to work itself into the pins. When reapplying, do so only by listening to your chain, not by its appearance. Use soap and water to clean the chain prior to reapplication -- strong solvents and degreasers will remove the protective plastic plating from the chain, putting you back at square one. Allow three applications to achieve optimum plastic plating.

Dumonde Tech offers two versions of their BCL, the Lite (which we recommend for road bikes) and the Original (which we recommend for mountain bikes or for when you're readying for Paris-Roubaix). The Original is more concentrated than the Lite and excels in the most challenging conditions. The two BCL formulas are compatible and may be used interchangeably.

It's really not a lube, but rather a dry plastic coating. I no longer get that black chain mark on my clothes or leg, when I get near my chain. You need to reapply when your chain rattles. Started with a sample from a show, and needed the bigger amount for all my bikes.

I have used many different chain lubes in over 44 years of competitive roadmountain biking. Since I was introduced to Dumonde Tech about 15 years ago, I have only used one! DUMONDE TECH! A few drops is all that it takes. Wipe-off the excess and it permeates your chain thoroughly! As long as you clean your drive-train once or twice a season, I think it's the best. It will collect grime if you put it on too thick so use it sparingly. My drive-train lasts a lot longer with no pre-mature wear. Give it a try!

I moved from using ProGold for years (which is a very quick, clean and easy solution for chain maintenance) to Dumonde as my preferred lube. It requires less cleaning, (i.e. chain does not get dirty) and seems to keep the links rolling smoothly for longer. Nothing is perfect, but this comes close !! I've been using the 'Lite' version for road and the thicker stuff for off-road, MTB and cyclocross. They are all too expensive for a bit of solvent and a few drops of oil, but hey.. a bottle lasts about a year, so it won't break the bank.

I've used a bunch of different lubes over the years. This is the best I've come across so far. The trick, after applying to a clean chain, is to wipe off the excess. This means wiping the chain with a good rag while spinning the crank. Do this for 2-3 minutes. After your first ride on the freshly lubed chain, wipe it again until you get a fairly dry cloth. Dumonde claims you don't have relube it until you hear the chain start to make noise. I relube it when the chain looks particularly dry. Also, I like the Dumonde Regular better than the Lite since it seems to adhere longer to the links in the Northwest rain. Even with Dumonde, there will be a little bit of crud building up on the links. I push a Q-tip through the big links. And, another trick to get some of the crud off: Use a smooth hand cleaner such as Gojo or Fast Orange and apply to a paper towel. Then run the sides of the chain through the daubed paper towel to do a partial cleaning of the chain. (A thorough cleaning necessitates taking the chain off the bicycle and soaking it in gasoline or citrus degreaser.) My wife's SRAM 8-speed chain lasted 4500 miles using the Dumonde Lube. I replaced the chain when the 1.0 mark fell into the links using the Park chain stretch tool. The chain does look cleaner with this lube. And I dont have to reapply the lube right away after riding 1 to 2 hours in a fair to middling rain, as I used to do with some other lubes.

I use the original version of this lube more as it is one of the only lubes I have found to last more than a day or two in Portland rain. It is pretty thick yet doesn't get that dirty as long as you wipe off the excess after application. I generally use the lite on my road bike in the dry months as it is a bit cleaner. You can even mix the lite and original together to get whatever viscosity you want. I have tried pretty much every lube out there and this is my favorite.

Began using the lite (yellow bottle) formulation with a new 11 sp. road chain about 700 mi. ago. Drive train shifts crisply, longer than with wax-based lube I was using. Also reapplication is needed less often, no more than every 100 mi. in dry weather for me. Chain stays cleaner than with my old lube, especially if I don't over-lube. It also doesn't smell as bad. Instructions say to reapply when the drive train gets noisy. If you're used to lubing after every ride or two, this will take some getting used to. But the chain definitely stays cleaner with less lube, and still runs well. I don't write many reviews. But wanted to share this one because this product will save you time and take care of your chain and cogs too. Keep on riding!

I discovered Dumonde through their motorcycle chain lube but once I tried their bicycle lube, I'm blind to other lubes now. This is THE bicycle chain lube. It takes maybe 2 to 3 applications to fully coat a chain but once it's coated, it works like no other. Worth every dollar that you're going to spend on it. There are 8 bikes in my family, down from 9 just recently, and it takes me about 2 years to go through a 4 ounce bottle. Sure it costs more than Finish Line or Triflow, but it's the longest lasting and least maintenance lube I have ever come across. There's no need to look for anything else. It just works.

I have only used the Lite version for road biking in the dry. I have found that it lubricates very well and is fairly long lasting. The characteristic I really appreciate is how clean the chain wipes down with this product.

I use the Lite version on all of my road bikes. Living in Southern CA I normally don't need to worry about wet weather and the Lite is all I need. Before I started using the Dumonde Tech product my go-to was Rock and Roll Gold. I still consider the Rock and Roll product excellent, but I have found the Dumonde product to keep the chain cleaner. I still keep a bottle of the Rock and Roll Gold as a back up.

I prefer the lite for my road bikes chain but this stuff aint cheap I only use it on a clean dry drive train and only enough to

make the chain wet a drop on each link then shift over every sprocket to work it in evenly makes the chain run smooth clean and quiet like a sewing machine no extra residue buildup if road conditions are clear and dry

On the pricey side, but product works great. A little smelly in confined spaces. I clean my chain several times a month (I ride in all weather conditions) I have noticed chain is quieter and seems to spin easier after applying. Do not notice lubricant attracts dirt. I have tried many products, My favorite is a melted wax chain dipping. I no longer want to spend all that time to lube a chain. I am very satisfied with Dumonde Lube, I use the Lite Formula on my road bike.

Used this lube before and during this year's Dirty Kanza 200. After the mile 11-14 hike a bike section, I had peanut butter mud caked around my chain, rear tire, crankset, and front derailleur. I scraped it and squirted it clean with a water bottle and continued on. What else could I do? Reapplied at mile 70 checkpoint and then at 158 after dust, mud, grit and water crossings took their toll. I was starting to hear my chain work right before the second treatment at mile 158, so I guess their recommendations were followed. I am very pleased with the performance of Dumonde Tech original. AWOL, TourRide and Dumonde Tech-no mechanical failures!

I've tried so many different chain lubes for MTBing and most just fail.. Ideally you are looking for a lube that gets between the roller and stays in place to cushion the wear and tear a chain goes thru..

I use this lube on all bike chains road, cross and mtb. A little goes a long way and it lasts. I use the traditional lube not the light version and it goes on a little thick, but you do not need much to lube a chain. Like all oil based lubes, it does pick up dirt, but not nearly as quickly as most.

No other lubricant works as well. This product goes on and stays on without attracting a lot of dirt. A bottle goes a long way, because it stays on the chain, no dripping and you can apply it sparingly. I have found no other chain lubricant that compares. Great for mountain, road and cross bikes.

Just switched to Dumonde Tech Original based on all the great reviews I saw online as well as from coworkers and LBS mechanics.

I live in the Seattle area and commute to work as well as ride my bike for general transportation. So far I am very impressed. I completely cleaned my drive train and let it dry overnight before applying. I wiped the excess and then let it sit another day before riding. I couldn't believe how quiet my drive train was. I have never heard it (or not heard it) that quiet. We had a big windstorm recently followed by heavy rains so our roads and bike lanes are covered in rotting leaves, pine needles and other debris. My bike is filthy but somehow my drive train still looks like I just cleaned it.
